The F&V Lighting 3-Stud Battery Plate allows you to change a V-mount Battery Plate to that of a 3-stud Battery Plate on your F&V X-Series Lights or V-mount Battery System. Unscrew the four (4) screws located on the top of the current battery plate, allowing access to change your battery plate to a 3-Stud Battery Plate. The 3-Stud Battery Plate is not self-enclosed. It must be used in conjunction with an X-Series light panel or the V-mount Battery System.
